Hemodynamic compensation during acute normovolemic hemodilution.
To the Editor:—Acute normovolemic hemodilution (ANH) causes a reduction in arterial oxygen content because of reduced hemoglobin concentration. The primary compensatory mechanism during ANH is an increase in cardiac output to maintain systemic oxygen delivery. Therefore, the lower limit of an acceptable hemoglobin concentration is related to how low hemoglobin can be reduced without jeopardizin...
متن کاملAbsence of beneficial effect of acute normovolemic hemodilution combined with aprotinin on allogeneic blood transfusion requirements in cardiac surgery.
BACKGROUND The efficacy of acute normovolemic hemodilution (ANH) in decreasing allogeneic blood requirements remains controversial during cardiac surgery. METHODS In a prospective, randomized study, 80 adult cardiac surgical patients with normal cardiac function and no high risk of ischemic complications were subjected either to ANH, from a mean hematocrit of 43% to 28%, or to a control group...
متن کاملthe comparison of acute normovolemic hemodilution with allogenic blood transfusion in patients who underwent femoral fracture surgery
background: acute normovolemic hemodilution is an available technique to decrease the side effects of allogenic blood transfusion. the aim of this study was to compare acute normovolemic hemodilution with allogenic blood transfusion in adult patients who were scheduled for femoral fracture surgery. methods: in this randomized controlled trial, 50 patients were randomly allocated into two equal ...

متن کاملAcute decrease in renal microvascular PO2 during acute normovolemic hemodilution.
Large differences in the tolerance of organ systems to conditions of decreased O(2) delivery such as hemodilution exist. The kidney receives approximately 25% of the cardiac output and O(2) delivery is in excess of the oxygen demand under normal circumstances. In a rat model of acute normovolemic hemodilution (ANH), we studied the effect of reduced hematocrit on renal regional and microvascular...
